quote from 1850 plan- "PD 1850 and other drivers with an EBP over 125 and BL's over 28. For drivers with EBP's around 110 or lower use the 186 horn." Green is somewhere in between. Brown have the high EBP, but the BL is less than 28.

I just modded the list of scoop compatible drivers- http://forum.speakerplans.com/topic65235_post674154.html#674154 and worked out the EBP's
Does this seem accurate?

How high does the BL for the 186 cab have to be? (The 186 driver's BL is 22.94.) How low can the EBP be for the 186 cab (before it starts to suck for the cab) (The 186's EBP is 82.)

Surely the VAS parameters must have some impact of the cabs performance. What is a good VAS to have for the 186 cab? Approx?

have you looked at the pd 188 ebp of 133.6 and bl of 26.59?? i am wondering how they would perform in 1850/186 cab??
there is probably a good reason (which i havent herd about!!) as to why they are not mentioned?? but they are cheeper than the 186 and seem better suited to the horn on paper anyway???
i know they 100w less than 186 but would think bout 800w in each bin would still have good effect!! any thoughts??

yeah sure, horn resp says it would work, has a nice curve, stays within xmax. sorry i cant post the horn resp screens atm. but yeah looks good, should sound good!
ps. great work reality sound cheers

great work on compiling this chart mate. 
have you had any experience with any of these drivers in the 186 ??

Not yet. I do have all intentions of building some in the near future mind you. I also do have quite a bit of drivers to compare in them. Of course I will share my findings. Hoping to try modding the cab a bit too.

sounds good mate, you'll have to keep us posted on how it go's.
think i decided to go for the pd 186 in mine now, purely because some people ill be putting in with got 186 in their bins, so it'll all match up when it used together, and none of the drivers will work against one another.
if it wasn't for that probably would have looked for a second hand pd188 to try in one!!

So I am planning to build some 186s with Faital Pro W18N8-1000s. The BL is just shy of 28, at 27.6, but it seems that when I simulate in Hornresp, that the driver will behave almost identically in either the 1850 or 186 horn. Seems like there is xmax trouble at about 550watts, unless I up the compression ratio (cut a smaller baffle hole) to about 3:1, and then I lose some low extension but can push with 850 watts, and get more than 140dbs with four. Any thoughts?

Hey im a newbie on the speaker plans site...
I have a pair of eminence omega pro 18a's laying around... Currently there in a Reflex box - however i have 4 x 12" folded horns. I cannot for obvious reasons use the two boxes together,
What i'm asking is how would my drivers perform in a 186 Horn? is it worth my time building/buying the cab's ?
Thanks in advance,
Matt

I Just found the RCF LF18G401 The specs look very good for the 186 Horn. What do you guys think about it? I Want to Build 2-4 186 Horns.

Good evening everyone, I would like to build 4 Rog 1850 and I would like to put EIGHTEEN SOUND 18NLW9600 as a driver, what do you think? I'm open to advice.
Thank you all very much in advance

18NLW9601 is my fav 18" driver of all time.
Don't know differences between your choice and that, but I would suggest B&C 18DS100 in the 186 horn, got to be good for 45hz in pairs.
1850 horn is a 50hz box, bit of a waste of 18sound, in there, IMHO.

Can the AD42 power the 18NLW9601? 2 per channel?

I've heard Void Inf8mk2, power 2x 4 ohm 18NLW9601 per channel, in Mini Scoops, and I was in shock.
Would not be the same, in 186/1850 horns though, as decent Mini scoop, with large chamber, effortlessly drops below 40hz, with that combo.

I should push it with 1 lab Grupen FP 9000 2 woofers per channel.
Recommend me some other top-of-the-range cases.
Thank you even in advance

Heya guys,
I am soon gonna get some Beyma 18G550's, and we were originally planning to build 4 1850 cabs. I know they aren't exactly optimal for the 1850's, but what is the chance of distortion, or damage to the driver at high volumes. Is it simply that they don't give the absolutely highest output, or should I really not build 1850's? Would 186 be a better option? Or should I really just build a different cab/get a different driver. We are hoping to reach 35hz or so with 4 subs, is this realistic?
Really appreciate any advice:)

35hz is not possible even with better drivers, beymas u want to mount will burn , 45hz is possible but still the driver is not optimal, look for higher BL driver or different cab

What about something like the Oberton 18XB1300, the specs a way closer to the 1850’s, but still lacking a little bit. BL’s at 28.3 compared to 30.99. Is this close enough that it should be able to work, or still not good enough. Or possibly in a 186 cab since the EBP is around 120. Problem is that it is impossible to find 4 sub drivers that are similar to the 1850’s on any secondhand marketplaces here. I’ve been looking extensively.

I once had approx 13x, of the "original" Oberton 18XB1300's.
The originals were great, but then Oberton modified the design, and they started failing.
I sent back most of my units.
I would say, B&C 18DS100 would be one of the best drivers, in the 186 Horn today.
Xmax/Xvar/BL, "maybe" sufficient, to run 186 horns, down to 42hz in pairs.

I think the ones I have a chance to buy are the original 1300’s. So you would recommend getting them to out in 186’s, if I have the chance?

They may work well, but I suggested 18DS100, because it has better Xmax/BL.
186 Horn not natively designed to do 40hz in pairs, so driver with extended Xmax needed, to get cab lower than 48hz in pairs, with SPL.
